As your body turns into that of a man, you get the ability to ejaculate semen, a clear to milky liquid that carries the spermatazoa, or just 'sperm' cells that can start a pregnancy in a female. When you dream, you have sexy dreams when you are in puberty. They cause your sex organs to activate. Your penis grows hard and longer, and semen is ejaculated (squirted) through the penis. It is absolutely and 100% normal.

A period is when menstruation occurs. Basically, an ovum (egg) is released from either ovary. The egg travels through the fallopian tube connected to the ovary and, eventually, it enters the endometrium. While the egg was traveling, the endometrium was thickening. If the egg has not been fertilized by sperm, it evaporates. The endometrium is not needed. The endometrium leaves the body through the vagina as a reddish fluid. This is a period.
